Yeah a tune will do you no good if theres something up with the car as it is like a bad plug wire or something. I would ask the individual who you got it from if it has already been tuned. Anytime you add a cam or do something to that extent with the motor, a tune is almost mandatory for the thing to run even somewhat okay. I have a feeling that if it seems good most of the time to you that it has already been tuned (that and I can't see the guy who rebuilt it doing that stuff and NOT getting it tuned).

A mail order tune from Madz28 or PCM's for less will get you a pretty good tune that should make the car run pretty well. Both will cost about the same (around $125 or so for the mail order tune). If you really want it 100% top notch dialed in tuning wise a dyno tune is the way to go, but yeah on average you can expect to pay $500+. I would go the mail order tune route if it were me with those mods done and be happy. But something as modded as my Z28 in my sig, and a dyno tune is a must. Again, I don't think the problem is in the tune though with your car.
